IMPROVEMENT IN AUTOMATIC FLY-BRUSHES.

Specilication forming part of Letters Patent No. 150,673, dated May 12, 1874; application led January 3, 1874.

To all whom it may concern.

Be it known that I, JOHN T. BENDER, of Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Mechanical Fly-Brushes, and that the following is a full, clear, and eX- act specificationv thereof, which will enableV others skilled in the art to make and use the said invention.

My invention relates tothe construction of a mechanical fly-brush designed for use on dining-tables or over sleeping persons for driving away flies and insects; and it consists in the combination of a geared lever, cam, and train of clock-work with the pinion and shaft of an oscillating fly-brush, by means of which a motion is given to the brush very similar to that given to it by a person when using it, as is hereinafter more fully shown.

In the accompanying drawings, Figure l is a side view of my apparatus, the side and cap of the case removed. Fig. 2 is a plan of the same with the brush and case-cap removed. Figs. 3 are side viewand plan of the cam and pinion. Fig. 4 is a plan of geared lever, and

Fig. 5 is a side view of brush-hold er.

B is the pedestal of the apparatus, and A the case containing the mechanism. O C is the frame for clock-work, in which is placed the main driving-wheel H, mounted on shaft Gr and driven by spring F. The wheel H meshes into the pinion I, on the shaft of which is the wheel J which meshes into pinion K, on the shaft of which is the cam L. The bracket D is secured to frame C over the wheel J, and has secured on it another bracket, E, and in these brackets is mounted the shaft O, on which is the pinion N, and at the head of which is the head P, to which the fly-brush is attached. The geared lever M is pivoted to a post, f, in frame C, and has a rack, U,.which engages with the pinion N; and on the arms h h at its end are secured the rollers 7c 7d, which stand down On each side of the cam L, as shown in Figs. l and 2. The cam L is made with three arms, l Z l, and has its center m placed eccentric to the shaft of the pinion K, as shown in Fig. 3. The brush-holder Q has two staples or eyes, e c, in which the shaft It of the fly-brush S is inserted, and it is 'piva oted, at T, to the head P, on which is the curved arm a, to which the holder Q can be clamped at any point by the screw d, thus holding the brush at any desired elevation, the head b on arm a preventing the brush from fallin g at any time below a horizontal position. The spring F is wound up by a key applied to shaft G, on which is the ordinary ratchet-wheel and pawl used in clock-work; and on motion being thus communicated to the gear-train H I J K the cam L will be revolved, thus causing the lever M to vibrate' back and forth by the action of said cam on the rollers 7c on the arms 71. of said lever, and this will cause an oscillation of the brush-shaft O by the action of the rack U on the pinion N, thus causing the fly-brush S to swing back and forth over the table in a manner readily seen. The cam L being placed eccentrically on the shaft of pinion K causes the brush S to move back and forth between the lines X X', Fig. 2, and then to move over and vibrate between the lines Y Y on the other side of the table, thus imitating in a most perfect manner the movements of a person driving the ilies first from one end of the table and then from the other.

When more power is desired for winding up the spring F, a gear-wheel can be placed on the shaft G, and a second shaft with pinions secured on the frame (l, to gear into said wheel, when the winding-key can be applied to said second shaft, by which means suflicient power can be attained to drive the ordinary-sized brush from one to two hours, which is as long as will be ordinarily required.

YVhat I claim as my invention, and desire to secure by Letters Patent, is

l. The cam L, actuated by a gear-train, and acting, through the lever M or its equivalent, to produce the oscillating movements of the ily-brush S, substantially as and for the pur-A pose specified.

2. The cam L, eccentrically arranged on the shaft of its pinion K, and acting, through the lever M or its equivalent, to produce the twoJ sided oscillating movement, of the fly-brush S, substantially as and for the purpose herein specified.

3. The lever M, with rack-gear U and arms h Mila-ving rollers k k thereon, in combination with the oam L and pinion N on brushshaft O, the several parts being arranged to operate substantially as herein set forth.

4. The brush-holder Q, with staples e e and clamp-screw d, in combination with the head P, with curved arm d, substantially as and for the purpose specified. x

5. The combination of the gear-trainH IJ K,

actuated by spring F, cam L, lever M, with rollers 7c la', and rack U, shaft O, with pinion N and head P, and brush-holder Q, with brush S therein, the several parts being all arranged to operate substantially in the manner set forth. As evidence of the foregoing, Witness my hand this 22d day of December, A. D. 1873.
